Ketone Meter Breath

Breath Acetone Meters

Breath Acetone Meters

Acetone is produced when your body is burning fat, and this can be measured in your breath. There are now a growing number of options for measuring your breath acetone. The devices vary wildly in price, and I've found some of the cheaper options can be quite effective. In all cases, how you breathe when taking a measurement is critical to getting a consistent and accurate reading. Overall, I found that measuring breath acetone to be far more convenient, and far more useful than measuring blood ketone levels. Measuring breath acetone is vastly cheaper than blood tests, and obviously less painful. This allowed me to check my ketone levels throughout the day, enabling me to find more detailed information about how my body reacts to food and exercise. The Ketonix is an FDA approved device that is designed specifically as a breath acetone meter. This is the only device that will give you an acetone reading in Parts Per Million, but is expensive and I found it to be cumbersome to use and I've experienced more erroneous readings than with cheaper devices. A cheap breathalyzer can be used as an improvised breath acetone meter. While these devices are intended to measure alcohol intoxication through breast measurement, the cheaper devices also detect acetone. This means you have to get a cheap, low quality breathalyzer, as the better devices will filter out any acetone. (I like the Greenwon AT6000, (Price Not Available)). There's another dedicated breath acetone meter called Ketometer. It's cheaper than the Ketonix, but more expensive than a cheap breathalyzer. LEVL is a remarkably expensive device for measuring breath acetone, and it requires an ongoing subscription. At the time of writing, it's$699 + $49/month, which is too expensive for me to consider. One interesting note is Continue reading >>

Breath Vs Blood Ketone Testing

Breath Vs Blood Ketone Testing

Transcript of Breath vs Blood Ketone testing Studies show ... Breath Acetone: correlates well with glucose indicates ketogenesis e.g the breakdown of fatty acids in liver to ketones (burning fat). Blood Beta-hydroxybutyrate concentration is a product of ketogenesis and time. Breath vs Blood Testing Ketogenesis Liver Fatty acids AcetoAcetate Acetone Beta-hydroxybutyrate Study objects : healthy, non dieting, in a 12 hrs fasted state. They where fed with ketogenic liquids during 24 hours. Increased AcetoAcetate will produce Acetone and Beta-hydroxybutyrate from excess AcetoAcetate Findings Breath acetone correlates well with blood glucose. 5 day water fast Beta-hydroxybutyrate increases from 1.0 to 4.8 Acetone is high, increases after 4 days Glucose drops after 4 days Beta-hydroxybutyrate is a product of ketogenesis and time Acetone indicates ketogenesis High ketosis increases beta-hydroxybutyrate over time. Breath acetone correlates to glucose, beta-hydroxybutyrate does not. Reflections ... Why does it not correlate better? The "issue" is ... People have different levels of ketosis.

Why I Stopped Testing My Ketones On A Ketogenic Diet

Why I Stopped Testing My Ketones On A Ketogenic Diet

On measuring Ketones. Like many people, when I first started a Ketogenic diet in early 2014 I bought the Ketostix and just couldn’t wait to see the color change. And change it did! It was neat, and it provided motivation for me to continue. Eventually, I got a blood meter, a breath meter and spent lots of time (and money) testing ketones. Between a Ketonix Breath Ketone Analyzer, as well as dozens of blood ketone test strips, I’ve probably spent well over $500 testing ketones. The main thing I learned from my extensive ketone testing regimen is that the results vary widely and there’s little application to my goals. Eventually, I stopped testing and here are several reasons why: 1. Burning fatty acids from fat is the main benefit of a ketogenic diet On a ketogenic diet, some of the brain’s energetic demand is fueled by ketones, but the heart, muscles, etc. are fueled by fatty acids. Most of the energy we utilize both at rest and at sub-maximal exertion on a ketogenic diet is fatty acid, not ketones. Quoting Dr. Ron Rosedale on chasing ketones at the Keto Summit: “I don’t want people to have the mindset that it’s the ketones that are the benefit of the diet. They are a beneficial side effect, but the main benefit is that you are burning fatty acids from fat. The more fatty acids from fat you are burning, the less glucose you need to burn. And that’s really where you are getting the benefit…So ketones are great but the term ketogenic diet indicating that the diet is so good because you are generating all these ketones is a misinterpretation of the benefit. The main benefit is that you are burning fatty acids, and as a side effect of burning fatty acids you are producing ketones that your body can burn too!” 2. Urine Ketones aka “peetones” are ridic Continue reading >>

Testing For Ketones

Testing For Ketones

Testing for Ketones 3 Types of Ketones How to go about testing for Ketones? There are 3 types of ketone bodies. Acetone, Acetoacetate and Beta-Hydroxybutryate (BHB, though technically not really a ketone body) The body (the liver) converts long and medium chain fatty acids into BHB and Acetoacetate. BHB and Acetoacetate live in reversible equilibrium (they can transform back and forth). Acetoacetate can also be turned into acetone. After converted to acetone, it can not be converted back. Acetone is typically excreted through the urine or breath. If your body has been in ketosis for a while, you will see a reduction in acetoacetate. Muscles begin to use acetoacetate and turn it into Beta-Hydroxybutryate for fuel, so less is present in urine as you get more keto-adapted. This is the flaw of the urine test. It only tests for acetoacetate so it will go down as your body gets more efficient at using ketones for fuel. 3 Methods for Testing Ketones Urine strips only test acetoacetate. Ketonix only tests acetone in breath. Blood Strips test for Beta-Hydroxybutryate (BHB), what your body uses for fuel. 1. Urine Test Strips Pros: Cheap. Cons: Very inaccurate in testing level of ketosis. Our bodies excrete excess ketones in two ways. Through the urine or through the breath. When you are testing for ketones in urine you will typically see higher levels in early stages of a ketogenic diet because your body isn’t using ketones for fuel yet. After you are fully Keto-Adapted (2-4 weeks or so), you will see less and less ketones in your urine because your body in now using more ketones for fuel instead of excreting them through the urine or breath. The urine test strip is also very susceptible to changes based on your state of hydration. The more hydrated you are (and we should all b Continue reading >>

Breath Acetone As Biomarker For Lipid Oxidation And Early Ketone Detection

Breath Acetone As Biomarker For Lipid Oxidation And Early Ketone Detection

Abstract Former ketone studies, including ketoacidosis (KAD), fasting ketosis (FK), nutritional ketosis (NK), and exercis-eaffected ketosis have brought great advances to the field of ketones. In the present work, blood, urine and breath ketone detections were evaluated systematically. We found that breath ketone (acetone) is the ketone of choice for detecting early stages of ketosis. In addition, acetone was correlated with respiratory quotient, and found to be a highly sensitive non-invasive biomarker of lipid oxidation. Furthermore, acetone was used for fast screening of ketosis or ketoacidosis in populations, and demonstrated value upon screening a population of 48 individuals, among which a type I diabetes case with early symptoms of KAD and FK case were identified.

How To Measure Ketones And Optimize Ketogenic Diets

How To Measure Ketones And Optimize Ketogenic Diets

The problem with diets is that we think that one diet should be good for everyone. But research and N=1 experiments show that’s not the case. Learn about measuring ketones and ketosis to understand how your low carb or high fat diet is really affecting you. If there is one area of our bodies that is debated to extremes, with literally hundreds of differing strong opinions on it, it’s nutrition. For many, beliefs about nutrition and diet are tribal. We put ourselves in different camps and we war agains the other camps. Whether it be paleo, low fat, low carb, Atkins, high fat, low protein, vegan, raw vegan and so on. It’s exactly this sort of area where I see data as essential. Without data we have no hope of cutting through the maze of opinions to get to what really works. Part of the problem with nutrition and diets is that we tend to think that one diet should be good for everyone. But increasingly, research and N=1 experiments, are showing that that isn’t the case. And this is exactly why you should pay attention to today’s show. Today, we’re looking at what has relatively recently become the fastest growing nutrition or diet trend. The high fat diet. Also known in different guises as the ketogenic diet, or the low carb diet. And specifically how this can affect our different individual biochemistries, how we can measure “Ketosis” and other biomarkers to understand how our specific biology is reacting to it… and allowing us to troubleshoot and course correct when it isn’t getting the desired results we’re looking for from it. Today’s guest is Jimmy Moore. In 2004, Jimmy, at 32 years, weighed 410 pounds. Since then he has transformed his own biology, shedding all that additional weight with low carb and ketogenic diets.

Continuous Monitoring Of Breath Acetone, Blood Glucose And Blood Ketone In 20 Type 1 Diabetic Outpatients Over 30 Days

Continuous Monitoring Of Breath Acetone, Blood Glucose And Blood Ketone In 20 Type 1 Diabetic Outpatients Over 30 Days

Corresponding Author: Chuji Wang, Department of Physics and Astronomy, Mississippi State University, Starkville, MS 39759, USA, Tel: +16623259455, Fax: +16623258898, Email: [email protected] Abstract Although breath acetone (BA) has been identified as a breath biomarker for some abnormal metabolic status, such as diabetic ketoacidosis, diabetes under insulin treatments, on a ketogenic diet, heart congestion failure, and post intense exercises, many intra-individual biological parameters also influence the breath acetone concentration. Therefore, it would be insightful to study longitudinal variations of breath acetone concentration in given individuals that have no baseline effect resulting from individual physiological heterogeneity. We carried out a daily-based continuous monitoring of BA, blood glucose (BG), and blood ketone (BK) in 20 type 1 diabetic (T1D) outpatients and 5 healthy volunteers over a period of 30 days. 600 breath samples from the T1D outpatients and the healthy subjects were collected and tested. BA was measured using a cavity ringdown BA analyzer. Simultaneous BG and BK levels were also measured using a standard BG/ketone meter. Our findings include: (1) The T1D subjects have elevated mean BA concentrations as compared to the controls. (2) There exists a positive correlation (R=0.57, P<0.05) between the individual mean BA concentration and the individual mean BK in the 20 T1D outpatients. (3) Some adverse or abnormal physiological conditions such as diabetic ketoacidosis, low body mass index or a special daily activity (e.g., exercises) can be identified via an abnormal BA concentration. This study suggests that continuous monitoring BA is useful in monitoring some abnormal physiological status such as T1D outpatients with very high BG or ketone bod Continue reading >>

The Best Ketone Meters To Monitor Ketosis – Christmas 2017

The Best Ketone Meters To Monitor Ketosis – Christmas 2017

The goal of a high-fat, low-carb diet is to get into a state called Ketosis where the body burns fat as fuel rather than using glucose as its source of energy. Types of Ketone Meters There are several types of ketone meters available that monitor ketosis in vastly different ways, some more accurate than others and some more convenient others. We’ll discuss 3 types of Ketone Meters available starting with the best on the market today in 2017. Ketonix Breath Ketone Analyzer The Ketonix breath analyser doesn’t use any blood glucose test or test strip, it works by analysing acetone on your breath that your body produces when you’re in a state of ketosis. The Ketonix is slightly less accurate as blood ketone and glucose meters are per test. But they are more convenient With the Ketonix, you can test yourself an unlimited amount of times, hourly if you like. Which is ideal if you want to see how various foods effect ketosis after you’ve eaten them or even the effects exercise has. The Ketonix is affordable when you take into account the price of test strips for blood monitors. (Many companies give away cheap versions of blood monitors but make their money on testing strips). The Ketonix has no test strips and requires no further outlay. Ketonix also comes with software that will keep a log and also calibrates the device to the optimal settings for your goals. If you’re trying to monitor ketones under conditions such as athletic performance, weight loss, diabetes, alzheimer’s or epilepsy. The Ketonix adjusts its settings to test whether you’re in the ideal range for that condition. The Ketonix Breath Ketone Analyzer is a one-off payment you can read more & check them out here.

Measuring Ketosis With Ketone Strips: Are They Accurate?

Measuring Ketosis With Ketone Strips: Are They Accurate?

Many people following keto diets want to be in ketosis, a natural state in which the body burns fat for fuel. For this reason, people are curious about whether they are doing enough (via carb restriction) to achieve this state. As a result, ketone strips are a popular tool that numerous people use as a way of measuring ketosis. However, just how accurate are they? And how do they compare to alternate methods of measuring ketones? What is Ketosis? Anyone following a standard high-carbohydrate diet will be burning glucose for energy. However, the body can use both carbohydrate and fat for fuel (1). When carbohydrate intake is very low, the body switches to burning fat for energy. As this happens, our body enters a state of ketosis. Ketosis is a natural biological state during which our body burns fat for fuel. While we are “in ketosis,” our blood levels of ketones—a by-product from the breakdown of fats—rise. Measuring these ketones (also known as ‘ketone bodies’) can, therefore, provide a hint as to how deeply our body is (or isn’t) in ketosis. For this reason, ketone strips—which measure the level of ketones—have become increasingly popular in recent times. Key Point: Ketosis is a biological state where the human body burns fat rather than carbs. What are Ketone Test Strips? For people who want to know if they’re in ketosis, ketone test strips are a cheap and simple way of detecting ketone levels. They are otherwise known as ‘ketone sticks’ and work by urinalysis to tell us the volume of acetoacetate in our urine. If you don’t know what acetoacetate is, then let’s start at the beginning. First of all, there are three types of ketone body; Acetoacetate Acetoacetate is one of the two main ketone bodies, and it is present in urine. We can test f Continue reading >>

How To Use The Ketonix Breathalyzer

How To Use The Ketonix Breathalyzer

A few months ago, I received my first keto breathalyzer and would like to share my thoughts on this device. The creator of the Ketonix breathalyzer, Michel Lundell, also runs a website to help and support people who use the device for measuring their ketone levels. The price of Ketonix is $ 149 (or $ 169 with the battery). You can buy the Ketonix breathalyzer at Ketonix.com. I was given this device free of charge and I'm not affiliated with Ketonix. The opinions expressed and photos in this post are my own. Measuring Ketones in a Nutshell Before I get to details of how to use the Ketonix breathalyzer, I'd like to start with some basic facts. There are 4 ways to measure your ketone levels: Ketostix. It measures urinary ketones (acetoacetate), is inexpensive but inaccurate because it only measures "wasted" ketones in your urine. In fact, once you get keto-adapted, you may not be able to measure any. Blood Ketone Meter. It measures beta-bydroxybutryate (BHB) and is the most accurate method of measuring ketones (although BHB is not technically a ketone). The drawback is that the strips are fairly expensive, especially if you measure frequently. Observation and following a healthy ketogenic diet. In my opinion, if you don't follow a keto diet for therapeutic purposes (or for performance enhancement), you don't need to measure your ketone levels. In fact, you don't need to follow a very low-carb diet to lose weight. What matters is finding your personal carb intake and also consider other factors that I explained here. Breathalyzer (Ketonix). It measures acetone (acetone is made from a break down of acetoacetate). It's great value for money as it's a one-off payment, there is no need to buy expensive strips and it's accurate enough to tell you whether or not you are in nutrit Continue reading >>

Japanese Researchers Create Smartphone Ketone Meter

Japanese Researchers Create Smartphone Ketone Meter

Researchers at Japan’s giant telecom, NTT Docomo, recently created a smartphone ketone (acetone) reader that may help low carb and ketogenic dieters stay aware of how their food choices affect their nutritional ketosis. Currently, the best approach for doing this is quite expensive: serum ketone monitoring. With ketone test strips running between $2-$5 USD a strip, measuring even once or twice a day with a device like the Abbot Laboratories Precision Xtra Glucose and Ketone Monitoring System can be a costly proposition. The alternative, of course, is cheaper but less meaningful ketostix that measure one type of ketone that is secreted in the urine, to varying degrees. (For additional background on ketosis and measuring ketones, see Why You Need To Stop Worrying About The Color Of Your Ketostix.) But if the researchers at NTT Docomo have their way, the cruel economics of ketone testing may change for the better: Acetone contained in our exhaled breath is a metabolic product of the breakdown of body fat and is expected to be a good indicator of fat-burning. Typically, gas chromatography or mass spectrometry are used to measure low-concentration compounds in breath but such large instruments are not suitable for daily use by diet-conscious people. Here, we prototype a portable breath acetone analyzer that has two types of semiconductor-based gas sensors with different sensitivity characteristics, enabling the acetone concentration to be calculated while taking into account the presence of ethanol, hydrogen, and humidity (source). Finally, the prospect of ketone measurements that won’t break the bank. The paper is an interesting read. Mind you, while this is encouraging news, we’re a long way from having consumer devices available for us to use. In fact, it may be tha Continue reading >>

Advantages Using Ketonix

Advantages Using Ketonix

KETONIX is an excellent alternative to monitor and record your levels of ketosis compared to urine and blood tests. KETONIX Ketone Breath Monitor is a one-time cost and is simple to use while being extremely portable and robust. It has never been easier to see and monitor metabolic ketone production So what are the advantages of using KETONIX instead of urine strips and/or blood ketone meters? KETONIX vs. Urine Strips Urine strips indicate the excess concentration of Acetoacetate in the urine. KETONIX indicates the acetone in your breath. Acetone is produced from the breakdown of acetoacetate in blood. Measurement units are not the same as the concentration of acetoacetate in blood is higher due to less volume (higher density) and is typically measured in mmol/l. The concentration of acetone in breath is lower due to much more volume (lower density) and is measured in PPM. Again, urine strips measures acetoacetate in urine, blood meters measures beta-hydroxybutyrate in blood and KETONIX measures acetone in breath (air). Urine strips can only be used once. KETONIX is reusable and can be used over and over again. Urine strips show a historical value of the excess production. KETONIX shows a real-time value of what is in the blood via exhaled ketones! Urine strips tests need urine and somewhere private to do the test. You can perform tests using KETONIX wherever you can access a powered USB port or the optional KETONIX battery pack. KETONIX may be stored in the bag that was included with the product. Urine strips cost per test. KETONIX is a one-time investment! KETONIX vs. Blood Ketone Meter Blood ketone meters measures Beta-Hydroxybutyrate in blood, not Acetoacetate or acetone. Blood ketone measure requires test strips which are expensive and often require a prescription. Continue reading >>

Ketonix Review

Ketonix Review

I picked up the Ketonix Acetone Breathalyzer a little over a month ago and have been playing with it ever since. I wanted to know how accurate it was in detecting ketosis compared to the current gold standard, which are blood levels of beta-hydroxybutyrate (BHBA). I purchased this device directly from the source at www.ketonix.com based out of Sweden. The system I use to test my blood levels of BHOB is the Precision Xtra Blood Glucose and Ketone Meter (if you want to find out where to pick up strips for this you can check out this post). The way the ketonix works is very simple. You just have to blow into the mouth piece. That’s it! Then the machine displays a certain colored LED light which corresponds to a certain breath acetone range. The device itself is about the size of a large marker. The USB cord is attached at the base. The cord itself is about 3 feet in length, giving plenty of slack when testing. The mouthpiece is detachable which makes it easy to wash, especially since the portion containing the electronics is not supposed to come into contact with water. It’s important to know that when reattaching the mouthpiece, there are tiny round cutouts in the plastic that need to be lined up in order to release the air the you blow into it. If these aren’t lined up, the air will have no where to go, and it will feel like you’re blowing into a closed system. I’m a little embarrassed to say that it took me a few tries of blowing into it with the air not moving anywhere to figure this out… Here are the official instructions on the label affixed to the device: Connect to USB port Wait until LED turns blue Blow gently into mouthpiece for 10-20 seconds Read color after 30 seconds This is what each different colored LED represents: Blue = 0 – 150 nmol/L Green Continue reading >>
